M To all whpm it may concern:

vBe it known that I Gnomes A. Misti-N, a slib'ectof the Emperor ofAustria, residing at ilwaukie, in the county of (llackamas and State. ofOre on, have invented certain new and useful mprovements in ShadowlessLanterns; and I do declare the follr'min to be a full, clear, and exactdescription reon'st 'ing. of an oil tank,

It is to over- .come this difliculty that thepresent invcn- 3 :tion. isldevised, and to this end it consists of a.supporting base which is made of co m- 1 paratively thin! and lightmaterial which "preciable amount.

' further object of the invention is to 1 generally ixnprove upondevices ofthis class y the provision of a comparatively simple, I andInexpensive construe tion, one which will be efficient and reliable inoperation, and well adapted to the purpose for which it is designed.

With these and numerou's other objects 'inview, the. invention consistsof certain hotel features of construction, and the combination'andarrangement of parts as will be hereinafter fully described and cleimed.In the accompanying drawings in which i ate, like view through a lanternconstructed in acon t e plane indicated by the with this nvention; a F i2 is a horizontal sectional view taken line 2-+2 of p h v ig. 3 1s avertical sectional view of a portion a lantern illustrating the mannerin wh-ieh the- 'loli'e isfixed to the same and 'illfltretingpt in itstwo positions;

indicated bythe line 4-4 of .Fig. '1; and,

Fig. 5 a detail sectional view taken: on the plane indicated Fig. l. k eA o Referring more particularly to the drawings. the muncral 1designates wfuei tank, which is of cylindrical construction, having :1convex'o, concave top 2 secured thereon in any suitable manner andprovided with a filling opening 3 hovin a, cap 4 fitted therein. The cap4 is provi ed with an inwardly opening spring pressed valve 5 in orderthat air may be pum ed into the tank should it. be found that" tie forceof gravity is not suflicicnt. to cause the 'fuel to run to the burner)Thebottoinol the tenk 1 is pro-- vided with n downwardly projectingeccen tricaliy :u'raned nip 'ilefi, the purpose of which will beiereinafter described.

The nipple extends through suitable openings arranged in an asbestosplate 7 and a metallic crown plate 8. the latter forming the top of acylindricalcasing 9. As shown, the upper end 'of the casin Sis providedwith a horizontally dispose outwardly-extending annular flange 10, andhas its u per side contacting with the lower side of the by the line 5-5of plate 8 and is secured thereto by means of V )OltS 11, whichhave anadditional function to be hereinafter described. The Walls of i thecasing 9 are perforated as at 12 to provide proper ventilation in thesame, as will be obvious.

Threaded to the nipple 6 is the upper end of a short tube section 13,the lower end of which is likewise secured to a small casing 14 having aneedie valve 15 mounted therein. The stem of this-Valve extends throughone of the erforaticrlltin thewgll of the casing tel pipe section 17contains a, wick AU-of suitable material, and threadhemp or other end ofthis pipe section is a ed in the free nozzle 21. p

The mixing chamber 19 constitutes the IQQ vertically disaosed portion ofa casing having inverted -shaped portions 22 communieating with saidvertically disposed portion by means of a narrow neck 23. This casing isarran ed beneath the crown. plate 8 centrally o the same, and secured tereto by a bolt 24 which extends through the crown plate and through alug formed on the top of said casing. Formed at the to of the i0 casingon the interior of the same a ove the neck 23 and between the invertedU-shaped ortions 22, is a rib 25, the purpose of which 18 to divide thegases as they pass from the mixingchamber 19 through the neck 23 andcause them to flow around the U-shaped portions 22 into tubes 26 whichare threaded at their upper ends to said U-shaped portions and which areprovided at their lower ends with suitable burnersin the form ofincandescent mantles 27. As shown, these mantles 27 are disposed asuitabledistance below the plane of the lower end of the casing 9.

The mixing chamber 19 is provided with an internally threaded opening inone side thereof in which is fitted the inner end of an air pipe 28.This air pipe 28 inclines downwardly from its point of connection withthe mixin chamber and has its outer end exten'de through the wall of thecasing 9 near the lower'end of the same and curved downwardly. By thisconstruction air from the outside atmosphere may .be conveyed into themixing chamber without any dange of rain or dust gaining entrance to thesame.

as The numerals 29 represent inwardl extending stops which are securedto the inner wall of the; casing 9 near the lower end of the same.Resting against these stops 29 is the annular flange 30 formed at theupper endof an inverted transparent globe 31, the

lower end of which is provided with air inlet openings This flange 30extends outwardly of the globe and is of a diameter substantially equalto theinternal diameter of the casing 9, to cause a rather snug fittingin the lowenend of the same.

Secured to one side of the casing 9 is a lug 33 having an eye at itslower end which forms a hinged portion for a U-shaped resilient 60clamping member 34. This member34 surrounds the major portion of theglobe 31 directly beneath the flange 30 and holds it in hinged relationwith respect to the cas-' ing 9. Secured to the other side of the easing9 is a resilient hook 35, the hooked portion of which is adapted to enage the lower side of the flange 30 of the g obe 31. This constructionprovides a meansi'or connecting the globe to the casing 9, and yetpermits the former do be swung out of the way when lighting tlrelantern.

The supporting base for the lantern coin prises an nnular base member 36which is arranged horizontally below the lowermost l5 portion of theglobe 31. Secured at their causes a partial vaporization o the fuel be:

lower ends by rivets .or otherwise to this annular base member 36 is aplurality of substantially upright standards 37 These standards 37consist of fiat strips and have their upper ends bent ir lteegrally asat 38 over the heretofore mentio flange 10 and ground late 8, and aresecured to these parts by the olts 11. The stri are then struck upwardlyand have t eir extreme ends offset outwardly to form ears 39 to 'whichare pivoted the lower ends of a bail-shaped handle 40.

The intermediate portions of the strips or standards 37 are twisted intoplanes .disposed at right-angles to their ends so that 80 they extendedge to edge in radial directions in order not to form an obstruction tothe rays of light from the burners.

nusing the device, suitable h drocarbon fuel 18 placed in the tank 1 andom this it passes through the ipe section 13 into the valve chamber 14.he valve 15 controls the sup ly of fuel into the pi e section 17. Thewic 20 disposed within t is'pi 0 section 17 D0 fore it reaches thenozzle 21,'a coin lete v'aporization taking place as it issues in thelatter in the form of a spray and mixes with the air conveyed into themixing chamber through the pipe 28. The mixed gases then pass upward ythrough the neck 23 and di vide, some ofi them assing downwardly throu bone o the tubes 26, while the remain er passes downwardly throu h theother tube 26. The heat from the urners 27 causes a quick .va orizationof the fuel. In first light n the antern it is necessary to heat thevarious arts with a match before applying it to t e burners. The ashes,tos plate 7 prevents the fuel tank 1 from becoming hfiated from the heatfrom the burners 27 and cons uently eliminates the danger of x losion ii the fuel.

From th: oregoing description, taken in connection with the accompanyingdrawings, it will be seen that the objects of the invention have beeneflectively carried out as-the supporting base of the lantern is 0 suchskeleton structure that it will not obstruct, an appreciable amount ofthcrays of light from the burners.

As various changes in form, proportion, and in the minor details ofconstruction may 'be resorted to without departing from the spirit ofthis invention, it is to be understood that I do not wish to be limitedto the precise construction herein shown and described.

I claim:
